Medical device repair is the work of maintaining and repairing medical equipment, which is mainly used in healthcare organizations and the medical field. Medical device repair requires medical knowledge and an understanding of relevant regulations, as medical equipment repair needs to comply with strict medical standards and safety requirements. In addition, medical device repairers need to understand the working principles and operating procedures of medical equipment so that they can accurately diagnose and repair malfunctions. Electrical appliance repair, on the other hand, refers to the maintenance and repair of general household or commercial appliances and has a wider range of applications. Appliance repairers need to have electrical knowledge and a grasp of relevant technologies to be able to recognize and fix electrical faults. They usually do not need to understand industry-specific expertise, but only the basic principles and techniques of electrical repair.
